ELECTRIC HAIR-BRUSH.

SPECIFICATION forming part of Letters Patent No. 627,295, dated June 20,1899.

Application filed December 81, 1898. Serial No. 700,815. (NomodeL) 7T0aZZ whom it may concern:

Be it known that l, ALoNZo H. BURCHARD, a citizen of the UnitedStates,residing at 0010- rado Springs, in the county of El Paso and State ofColorado, have invented new and useful Improvements in Electric Hair-Brushes, of which the following is a specification.

My invention relates to electric brushes in which the bristles are ofconducting material and the electric circuit made or established by thesaid bristles coming in contact with the flesh or hair of a person usingthe brush.

The object of the invention is to simplify the construction of suchbrushes and to otherwise improve the same, whereby they shall possesssuperior advantages with respect to efliciency in use.

The invention consists in the novel con struction and combination ofparts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a plan view of an electricbrush constructed in accordance with my invention, the cover to the backbeing removed to show the sectional or jointed battery. Fig. 2 is acentral longitudinal section. Fig. 3 is a transverse section on the liney y, Fig. 2. Fig. I is a bottom plan view, the bristles and thenonconducting strip being removed.

In the said drawings the reference-numeral 1 designates the body of thebrush, and 2 the handle, which may be made of any suitablenon-conducting material-such, for instance, as hard rubber. Formed inthe back of the 5 brush are two longitudinal recesses 3 and 4.

to receive the sections 5 and 6 of a galvanic battery. This batteryconsists of a number of zinc and copper plates separated from each otherby felt or other suitable material, which 0 is to be saturated withexciting material, as usual. The said plates are connected or jointedtogether by suitable conductors, and the two sections are connectedtogether at one end by an insulated conductor 7. The 5 opposite ends ofthe said sections are not connected to each other, but are provided withconducting-loops 8, which are connected with lugs 9, which extendthrough the back of the brush, and are formed integral with metallicconducting-plates 10 and 11, extending lon- 5o gitudinally along thefront of the body 2 and secured thereto by means of clips 12. Theseconducting-plates are separated from each other, so as to be out ofcontact. Secured to the said front is a strip 13 of soft rubber or'othersuitable non-conducting material, through which the bristles 14, of Wireor other conducting material, pass. These bristles, at their inner ends,are provided with heads 15, which are located between said strip andfront of the body and contact with the said plates 10 and 11, the headsof the bristles at one side of the brush contacting with plate 10, whilethose at the other side contact with the plate 11.

The numeral 16 designates the cover to the back of the brush.

The operation is as follows: The battery is excited by means of asuitable acid, with which the felt is saturated, and when the bristlesare placed in contact with the scalp, body, or other portion of apersonan electric circuit will be made or established as follows: from thepositive pole of the battery (marked A)to the lug 9 of plate 10, to saidplate to Q the bristles at one side of the brush, and from thencethrough the hair or flesh of the person to the bristles at the oppositeside of the brush to the plate 11, lug 9 thereof to the negative pole ofthe battery marked B.

Having thus fully described my invention, what I claim is In an electricbrush, the combination with the body and the bristles and non-conductingstrip and the battery and connections, of the positive and negativeconducting-plates interposed between the front of the brush and thenon-conducting strip and the clips for holding said plates in place,substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
